because your transmission get the heat from the coolant that is in your radiator. when engine get to normal temp, thermostat
open and hot coolant circulate to the tranny, as well as to heater.
in sub zero temp it takes a while

Ok. Everyone is a little bit right if they said that you have to let your car warm up in the warm weather. All cars run on fluids. Gas, tranny fluids,power steering fluid,anti-freeze, etc. Now while none of these fluids will freeze unless at like -35 or so temps, they do get thick and sludge like when cold. When you first start up your car they fluids are all in the pan and if you put the car in drive and hit the gas the fluid is not going to be where it needs that is why you hear cars "whining" when they pull away in the morning because the power steering fluid has not lubricated the pump enough and therefore has to work harder. The tranny fluid is all down in the pan and not lubricating the transmission and again when you put the car in gear it is putting the tranny under stress with no lubrication and that is causing unneccessary friction on the tranny parts.I can go on forever. The correct answer is to start it up and wait until you hear the engine quite down and see the RPM's drop that is a great guide to use to know if your car is warmed up enough. Remember the colder the temp and the longer it has sat there not started the longer you should let it warm up.,

The lube in the transmission is cold until it gets heat it will continue to shift more difficult. Your experiencing synchronizer ring drag. If I were you look around for some 100% synthetic manual trans. lube. It creates much less internal gear drag at low temperatures and is much more"slippery" than conventional gear lubes. Be sure all linkages to the trans. are lubricated too. I'm certain this will help a ton. Good Luck

the gear oil in the trans is very thick when its cold and when the oil warms up it thins out you can drop the weight. It more then likely is 85 - 140 you can drop the weight down to 80-90 it will worm a little quicker and should be easier to shift when it,s cold

Hm, I wonder how many have answered with 'Transmission Fluid' ... it is your GEARBOX oil not your transmission fluid that is behaving unreasonably, when was it last changed, did the car previously come from a warmer state/country.
You may need a lighter oil in the gearbox, it will likely be a 'Hypoid' maybe SAE 90. Check your manual or your local autoparts store, they usually give good advice.

Have you ever serviced the transmission? If this is only in cold weather the transmission oil may be to thick. Some of the newer vehicle use 30-W oil some use automatic transmission oil but most use 85/90w oil, or it may just be low on oil, have it checked and or serviced. Good Luck and GOD Bless

When it is very cold the (oil or trans fluid lube depending on the model car) in the trans will be thick like syrup. I would try to have the fluid changed and possibaly put in a additive.

The lubricating oil that is used for transmissions is considerably thicker than motor oil, and when it is cold it is like thick grease. It becomes much more liquid when it warms up, much like honey.

Because cold oil has greater viscosity than warm oil.
